This invention relates to an improvement in the construction of tops forpowder-flasks. In the construction, as heretofore practised, the top orneck has been formed from cast metal, having projections upon the insidewhich require to be turned into shape and then a flange or rim solderedthereto, making the construction expensive. To overcome or reduce thisexpense is the object of our invention, which consists in forming theneck and top plate from sheet metal struck up into the form required,whereby the turning and finishing heretofore required is avoided, and abetter article produced. I

A is the top plate, formed from sheet metal, with the flange B to extenddown on to and form the neck or head of the flask. For the tube oroutlet 0, we perforate the plate A and turn downward the'flange a,denoted in solid black, Fig. 3. Into this the tube 0 is fitted andfirmly secured. To form the mouth or cut-off, we attach a cap, 6, to theflange a, as denoted in Fig. 3. This is also formed from sheet metal tofit over and be secured to the flange a. The adjusting-tube H isarranged over the tube Gin the usual manner. The gate D is pivoted at d,in the usual manner, to a lever, E, by means of which the gate is turnedaway from the mouth, as denoted in broken lines, Fig. 3, and returned bya spring, 0, in the usual manner. By this construction the mouth isformed from sheet metal the exact size required, and therefore avoidsthe expense of finishing the top and its attachment to the flange B. Toform a bearing for the pivot 01, we turn down a flange, f, in likemanner as described for the flange a, and into this set and secure apiece, F, which forms a bearing for the pivot f. In order to affordmetal for the screw which secures the spring, as at G, I attach a pieceupon the under side in similar manner as described for the piece F, andto form a hearing or resistance for the spring, as at a, Fig. 4, whichhas usually been done by soldering a stud or point thereon or insertinga pin, we raise the metal by indenting from beneath, as seen at n, Fig.4. As heretofore attached, this projection or bearing for the spring hasbeen liable to displacement by use; but the projection thus formed beinga part of the metal of the cap cannot be detached, and is produced atmuch less expense than the attachment of the separate piece.

\Ve claim as our invention 1. The top or neck for a powder-flask,consisting of the plate A and flange B, when struck from one and thesame piece of sheet metal, substantially as described.

2. The plate or top A of the neck of a powder-flask having the flange 0.turned downward, when struck from a single piece of sheet metal, andcombined with the month I) and cut-off D, substantially as described.

3. In the top or plate A of a powder-flask neck, the flange fconstructed to receive the piece F, in the manner described, to form abearing for the pivot 01 of the lever E and cut-0E or gate D, as setforth.

4. The projection n'formed upon the plate A as a bearing for the springe, substantially as described.
